That would be true only IF humans are self-destructive by nature.
The truth is humans are not self-destructive by nature. Free will and selfishness is the central factor here. Everything a person does is a choice, and every choice he makes will affect himself. People can choose to make the right choice, or the wrong choice. Those that choose the former rises (productive), and those that choose the latter(self-destructive), falls.
That is the reality of man and his relation to the world.
Capitalism is the only econ-political system which recognize that relationship and sets justice as its standard. If you succeed, the fruit of your success belongs to you in full and no one can force you to give it up through law. If you fail, you carry the your burden of failure in full and the law prevents you from forcing others to share it.
So, if your definition of an utopia is a society where every man is GUARANTEED to succeed and/or be wealthy, then yes, human nature precludes that possibility.
My definition of an utopia, the utopia only a free capitalistic society allows, is one where those that choose to make the right choice and succeeds won't be dragged down with force by those that choose to make the wrong choice and fails.
That utopia is very much possible, and the only utopia possible to humans.
